How can we improve Copyright Clearance in Talis Aspire?

Change how locked down a pdf is after downloading it from a list

At the moment when you download a pdf from a list it is completely locked down. We would like the ability to add comments or annotations to the pdf once it has been downloaded. We don't want to change it so you can edit the pdf. Just add comments. TADC reduces the ability to have to print out lots of readings but it doesn't allow the students to write notes on the pdfs the way you would be able to from a paper copy. We believe this would save a lot of unnecessary printing.
